SINGAPORE (AP) — The United States set the world record in the 4×100 mixed relay on Saturday, clocking 3 minutes, 18.48 seconds in the swim world championships.

The old record was 3:18.83 set in 2023 by Australia.

It was only the second world mark set in these championships. It came on a night when the United States won three gold medals, by far its best performance in what had been a lackluster championships for the team.

Katie Ledecky won the 800 freestyle and Gretchen Walsh took the 50-meter butterfly. The Americans now have seven gold medals. The championships close on Sunday.
